...in that multiple stitches are 'active', or in use, at the same time, and crochet uses a single tool, a crochet hook, instead of a minimum of two knitting needles. The active stitches are held on a needle until another loop can be passed through them with a second needle.

Knitting may be done by hand or by machine. By hand, there are numerous styles and methods. Some of these produce an entirely different end-product; some produce very similar results. Flat knitting, which is done on two straight needles, produces a length of cloth, while circular knitting, which is done on circular or double-pointed needles, produces a seamless tube.

Different yarns and knitting needles may be used to achieve different end products, by giving the final piece different colour, texture, weight or integrity.

Weft knitting versus warp knitting

There are two major varieties of knitting: weft knitting and warp knitting. A weft-knitted fabric consists of horizontal, parallel courses of yarn and requires only a single yarn. By contrast, warp knitting requires one yarn for every stitch in the course, or horizontal row; these yarns make vertical parallel wales. Warp knitting is resistant to runs, and is common in lingerie fabric such as tricot. Warp knitting is generally done by machine, whereas weft knitting may be done by machine or by hand (Spencer 1989:11-12). Knitting machines use a different mechanical system to produce results nearly identical to those produced by hand-knitting.

Flat knitting versus circular knitting

Circular knitting (also called "knitting in the round") is a form of knitting that creates a seamless tube. Knitting is worked in rounds (the equivalent of rows in flat knitting) in a spiral. Originally, circular knitting was done using a set of four or five double-pointed knitting needles. Later, circular needles were invented. A circular needle resembles two short knitting needles connected by a cable between them. Flat knitting, on the other hand, is used, in its most basic form, to make flat, rectangular pieces of cloth. It is done with two straight knitting needles and is worked in rows, horizontal lines of stitches.

Circular knitting is employed to create pieces that are circular or tube-shaped, such as hats, socks, mittens, and sleeves. Flat knitting is usually used to knit flat pieces like scarves, blankets, afghans, and the backs and fronts of sweaters.
